Which of the following cells do not have a nucleus ? (A) white blood cells (B) red blood cells (C) neurons (D) bone cells

Options

A. white blood cells
B. red blood cells
C. neurons
D. bone cells

Answer

To solve the question "Which of the following cells do not have a nucleus?" we will analyze each option provided:

1. **White Blood Cells (WBCs)**:
- White blood cells are part of the immune system and play a crucial role in fighting infections. They do contain a nucleus, which is essential for their function in producing antibodies and other immune responses.

2. **Red Blood Cells (RBCs)**:
- Red blood cells are responsible for transporting oxygen throughout the body. They are unique in that they do not have a nucleus. This absence allows them to maximize the amount of hemoglobin they can carry, which is vital for their function in oxygen transport.

3. **Neurons**:
- Neurons are the fundamental units of the brain and nervous system. They do have a nucleus, which is important for the cell's metabolic activities and for processing information.

4. **Bone Cells**:
- Bone cells, including osteocytes, osteoblasts, and osteoclasts, all contain a nucleus. The nucleus is necessary for their role in bone formation and maintenance.

After analyzing all the options, we conclude that the correct answer is:

**(B) Red Blood Cells**
